Abstract (en)
[origin: US5712230A] This invention relates to a composition, comprising: (AT) reaction products of compounds represented by the formula (A)and compounds selected to reduce the polysulfide components of (A); and <IMAGE> (A) wherein in Formula (A), R1, R2, R3 and R4 are independently hydrocarbyl groups, X1 and X2 are independently O or S, and n is zero to 3 (B) an acylated nitrogen-containing compound having a substituent of at least 10 aliphatic carbon atoms. In one embodiment, the inventive composition further comprises (C) a second phosphorus compound other than (A), said second phosphorus compound being a phosphorus acid, phosphorus acid ester, phosphorus acid salt, or derivative thereof. In one embodiment, the inventive composition further comprises (D) an alkali or alkaline earth metal salt of an organic sulfur acid, carboxylic acid or phenol. In one embodiment, the inventive composition further comprises (E) a thiocarbamate In one embodiment the inventive composition further comprises (F), a non-phosphorous organodisulfide. These compositions are useful in providing lubricating compositions and functional fluids with enhanced antiwear properties.
